Busch Flapper, Buna Part# 300070 – vacstellar

Our flapper is the Busch part. This means it’s made to the exact original size and shape. It will fit perfectly in your pump’s valve plate.

It’s crafted from Buna rubber (also called Nitrile). This material is chosen for a reason. It stays flexible under pressure. It resists wear from oil and heat inside the pump. This ensures a long service life.

Replacing it is a common maintenance task. With a basic service kit and some care, you can often do it yourself. It’s a cost-effective way to revive your pump, much cheaper than a major repair or a new machine.

Using this flapper protects your investment. It helps your Busch pump run smoothly, efficiently, and quietly for years to come.

Don’t let a small, worn part cause big problems. Keep a spare on hand for quick maintenance.
